MACHINERY FOR PREPARING TEXTILE FIBERS.
Application filed April '17, 1926. Serial No. 102,787.
This invention is particularly applicable to the means for feeding fibers into carding engines, openers, scutchers and the like,
The principal object of this invention is to provide effective means whereby the cotton or other fiber being directed to the carding or other\ cylinders will be divested of a maximum amount of its impurities such as motes, shale, husks, and broken seeds, and at the sametime retaining nearly all the fibers which are long enough for spinning. The practice heretofore has been .to attempt to do this, but the best machines resulted ina material waste of the fibers by expelling them ling the air currents produced by the ordinary licker in or equivalent cylinder, and
while providing outlets for them which permit of the discharge of the impurities with them, also taking back into the machine "a currentof air close to the surface of the licker-in compressing it to. produce a swifter current, and then expelling it gently so asto take out the finer impurities after the coarser ones are removed. I I
The invention also involves improvements in details of construction of the mechanism for accomplishing these last mentioned results, including special perforated plates under the discharge side of the licker-in and the further provision of means for retaining the fibers along the surfaces of the card itself so that they will'not be wasted, but permitting impurities to be discharged all alongthe lower side thereof.
Other objects and advantages of the invention will appear hereinafter.
Reference is to be had to the accompany ing drawings in which Fig. 1 is a sectional view of the cylinder of a card and its feeding-in mechanism shown with a preferred form of this invention to illustrate their relationshipto each other;
Fig. 2 is an enlarged view of a similar nature showing principally the licker-in and the features of this invention which are associated therewith;
Fig. 3 is an enlarged sectional view of the concave guard plate which is located along the lower delivery side (if the licker-in; and
Fig. 4 is a'fragmentary plan of the same on reduced scale.
In the feeding of cotton or other fibers to a card or similar machine, the layer of fibers which have been matted together reviously, is fed along a table 10 to a feeding roll 11 and the'fibers are taken up b the licker-in 12 having numerous teeth on its surface and which rotates in the direction of the arrows in the drawings. This takes the material to the cylinder 13 which removes the fibers and performs its usual. functions.
The licker-in rotates at a high enough speed so that its teeth create currents of air, which to the best ,of my information have never been taken proper care of for -the purposes I have mentioned above. It has been common to place a bar of triangular cross section in a position to co-operate with the licker-in and grid for the general purpose of removing impurities, but it has had the effect that a large quantity of fibers, good for spinning, are removed by it and become waste so that they are lost for further treatment, As stated above, this invention is designed to reduce the loss by a very material percentage and at the same time produce a cleaner cotton or other material at the cylinder 13 itself. I do not necessarily make any change in the parts that have been referred to by numerals above. They work in the usual way.
For the purpose of gently directing the air away from the licker-in 12, I have pro vided two deflectors 14 and 15. These are shown mounted on plates 16 on the two sides of the machine, these plates being adjustable about pivots 9 on plates 8 which canbe adjusted horizontally. They are secured in adjusted positions by bolts 17 and 17 and slots 18 and 18 in fixed plates 7 on the two sides of the machine. tors 14 and 15 is mounted to be adjusted Each of the defiec- I sidewise by screws 19. These screws are air-,aaje. ,oompressed in the throat 25 and Theylextend all the way across the ma-* chine and provide two passages 21 and 22 through which the currents of air can pass from the licker-in and escape toward the bottom of the machine.- These currents of air carry with them most of the heavier particles that are mixed with the cotton or of other fiber, dropping into the waste box below, not shown}, These-dcflectors are adjusted to the most efiicient position by experiment.
The action is to allow many heavy particles to be separated from the fiber and yet not provide wide .enough spaces between the deflectors to permit very long fibers to be discharged in any great numbers. On account of this, more than the usual number of the long fibers that can be used in spinning are retained on the licker-in up to the space 23.
From this oint 'on the action is of a somewhat di erent character. Instead of providing for the expelling of the air I provide for inducing air currents from the space 25 into, the passage between the surface of the licker-in and a plate 24.- preferabl of sheetnietal. This plate is so located an shaped" that it leaves a wide throat 25 betweenfa'flat surface 26 thereon and the surfaoe of the licker-in capable of admitting currents .of air in the direction of the arrows. These currents are caused by the .rotation ofthe licker-in which takes t em-Yfrom'any available source and carries them-along with it. The currents of in a narrowing space 27 which is located between-the licker-in and a curved surface 28 extending from the wall 26 to the end of i the sheet metal plate 24. This curvature adually converges toward the points of te teeth of the licker-in. Therefore, the
- currents of air which enter the throat 25 have no point'of egress along the top of this ihg space all the way along. Therefore late 24, but they are forced into a narrowthey are compressed and the rapidity of the current is increased.
These currents mentioned, naturally take along the fine impurities which may be dropped out of the licker-in along the surface of the plate 24 and what loose particles there may be. As their rapidity increases in the manner above mentioned, they form a comparatively swift current at the end of the plate 24 and here, a passage 30 1s proout much loss- 0 vided toallowmuch of the air to escape suddenly. This, however, is a narrow passage as it is bounded on the front by a deflector 31 which preferably is of metal and extends throughout the length of the cylinder. This has a front surface which slants off gradually and gently and a sharp point at the top to stop the impurities which have slowed down enough to drop oil the licker-in instead of going along around with it. This, therefore, obviously tends to separate out some of the foreign particles from the fiber and yet there is little tendency to take any fibers from the licker-in because of' the narrowness of the passage 30 and because there is a current of air passing circumferentially around it which helps to hold them in place. What fibers are dropped here are likely to be very short ones and perhaps some that are heavier than the bulk of them for one reason or another.
I have shown four of these deflectors all shaped in a similar way and all providing gently sloping and gradually widening passages for the dispersal of the air. These deflectors are slanted back on their upper ends and this allows the air to expand a little when passes over the sharp points on the top, to slow down and drop out foreign particles in the currents. In this way the fiber is cleared most effectively of impurities not ordinarily taken out by any 'kind of knives or bars usually employed. The provision of means for separating out impurities in two ways, so that one means a series of oblong staggere' openings or slots 34. These openings, ev en if the walls were flat, would present a series of straightsurfaces. transverse to the direction of motion of the air, against which the air would necessarily press to a certain extent and thus perform a further; caning operation with- V M material amount of fiber. Butin addition-to the fact that I have these straight surfaces or walls, I shape the metal plate 32 so that each of the surfaces 35, against-which the air beats in passing along the concave side of this plate,
is bent inwardly to'form a further abutment and a' more efficient means for stopping many impurities that are heavler than the fiber itself.
To allow the air currents to pass out gently, I bend'the opposite end surface 36 outwardly to give a gentle curve at the corner surface over which the air is discharged without forming whirls or vortexes in the air currents. This, therefore, provides for a gentle exit of the air as has been described in'connection with the deflectors 31 and at the same timeon the other side of each opening, positive means 35 is shown for stopping the impurities and insuring their deposit below.-
-I continue this principle to an extent not heretofore adopted as far as I am aware, by providing two concave sheet metal plates 38 and 39, concentric with the cylinder 13 of the card and extending practicall throughout the lower surface thereof. hese two plates may be connected by cross bars 40 adjustably mounted on brackets 41 at the two ends of the machine and securing between the two cross bars the outwardly bent ends of these sheets. They are practically like the sheet metal plate- 32, having staggered oblong slots or openings provided with the edge rojections 35 and 36. In this we an additional cleaning is provided al the way along/the lower surface of the main cylinder of the card without danger of loss of any material portion of the good or long fiber.
The result of this arrangement is that the fibers delivered by ithe maln cylinder of the card are very much cleaner thananything that has been produced heretofore and the product is increased by a material percentage, owing to the fact that provisions are made, all the way'from the table 10 to substantially the delivery point of the main cylinder, for preventing the discharge of fibers which are not weighted by impurities and that are long enough for effective use in spinnin Although I have illustrated and described a preferred form of the invention inconsiderable detail, I am aware of the fact that modifications can be made therein by any person skilled in the art without departing fromv the scope of the invention as expressed in the claims, so long as the princi les herein set forth are retained.
